Overcoming disordered energy in light-matter interactions
Polaritons are formed by the strong coupling of light and matter. When they mix together, all the matter is excited simultaneously—referred to as delocalization. This delocalization has the unique ability to relay energy between matter that is otherwise not possible.
Disordered energy is ubiquitous in nature and the universe. Disordered energy is less organized and less available to do work, such as with heat dissipation. Even in plants, disorder can ruin effective energy transfer.
In the context of polaritons, as disorder increases, it can negatively affect light-matter interactions, including polariton-enabled energy transfers. Overcoming this disorder is an important topic across many scientific fields.
Breaking Barriers in Surface Chemistry: The autoSKZCAM Framework for Ionic Materials
Understanding and predicting chemical reactions on surfaces lies at the heart of modern materials science. From heterogeneous catalysis to energy storage and greenhouse gas sequestration, surface chemistry defines the efficiency and viability of advanced technologies. Yet, computationally modeling these processes with both accuracy and efficiency has been a grand challenge.
A recent study published in Nature Chemistry introduces a breakthrough: the autoSKZCAM framework, an automated and open-source method that applies correlated wavefunction theory (cWFT) to surfaces of ionic materials at costs comparable to density functional theory (DFT). This achievement not only bridges the accuracy gap but also enables routine, large-scale studies of surface processes with chemical accuracy.
What Are the Interferences to Radio Waves?
Radio interference refers to the phenomenon that occurs during radio communication, where some electromagnetic energy enters the receiving system or channel through direct or indirect coupling, resulting in a decrease in the quality of useful received signals, information errors or loss, or even blocking communication.
Radio interference signals are mainly electromagnetic energy that enters the receiving device channel or system through direct or indirect coupling. It can affect the reception of received signals required for radio communication, resulting in performance degradation, quality deterioration, information errors or loss, and even blocking the communication. Therefore, it is generally said that the fact that useless radio signals cause the quality of useful radio signals to decrease or damage is called radio interference.
Previously we have an article about t he analysis and solutions of antenna interference in satellite communication, including polarization interference, adjacent frequency interference, forwarding interference, etc. Please click here to read the full article. Today we will focus on analyzing how to interfere with radio from several aspects, such as physical obstacles, weather conditions, electromagnetic interference (EMI), solar activity, atmosphere, and frequency bands. For example, heavy rain can reduce the signal strength of 12 GHz by 20 dB per kilometer. Solutions include using higher frequencies to obtain clearer paths or placing antennas to avoid reflective surfaces and interference sources. Please go ahead for further details.
Sunlight-powered catalyst sets new standard for hydrogen peroxide production efficiency
Hydrogen peroxide (H2O2) packs so much chemical energy into a small space that it is powerful enough to fuel rockets. But this same ability to concentrate energy also makes hydrogen peroxide useful for more earthly energy applications, such as powering fuel cells. It also holds promise as a green and sustainable energy source: when hydrogen peroxide releases its stored energy, the main byproduct is simply water.
